Low end performance of F1 subs

I do not have the pleasure of owning a Bose F1 system, but I am very interested in buying one. I've read plenty of blogs/reviews and I like what I have seen so far. But there is still one question I have that is keeping me from taking the leap. 

I will be using this sound for live application. It'll be for a 4 piece "tejano/conjunto" band (vocals, button accordion, guitar, bass, and drums). This style of music is driven strongly by the bass line and drums, mainly the kick drum. So in turn I'm looking for a sound that can deliver a powerful "punchy" low end. I'm not to familiar with technical terminology so I hope "punchy" gives you an idea of what I need. 

I really would like the chance to listen to a F1 system in person but haven't had any luck finding something locally (Corpus Christi Texas area). So I truly hope someone on here can describe the type of low end performance they've notice from the F1 subs. 

Thanks for your time and input. 

P.S. I attached a short music clip so you can have an idea of the style of music I references in this post. (Best through headphones) 

This may or may not help but get to all the youtube videos out there on the F1, listen to them you will begin to hear how the F1 preforms noted through other video equipment but you will begin to get a feel for the F1s capabilities. Also you mentioned you are interested in purchasing a system. Places like Sweetwater allow you to demo a unit for a very short period of time, this may be one way to get your hands on something no one else carries in your neck of the woods. 

I've run this vid through my F1 system. The system will do quite nice for your style of music.
